I just won a barber's hone on ebay for really cheap and when I got it the front is kind of dirty and scratched but the back looks pristine. Can I just hone on the back of it? Probably a dumb question but I am sure you guys have the information I need. Also, the seller sent me a blade with it that is pretty rusty but in otherwise decent condition. It is marked "the winner" Sheffield. I will post pics later but does anyone know anything about it? Thanks!
